Smithsonite is a relatively rare gem when it comes to facetted stones. I have seen plenty of Smithsonite cabochons, but actual gemstones are not very common. This stone is nearly colorless (it has a very slight yellowish hue), and is slightly "hazy" which is common even in good Smithsonite gems. The stone has an Oval cut, and is a very good size, attractive gem of this material. One does not encounter many of these gems on the market, and no rare gem collection is complete without a good Tsumeb Smithsonite. This stone is one of a handful Smithsonites that I have had to offer in the last few years.
